1998-04-23 to 1998-06-01 data collection includes measurements of pH, alkalinity, salinity, temperature, dissolved oxygen, nutrients, and chlorofluorocarbons from the North Atlantic Ocean. The dataset was collected by researchers from the Commonwealth Scientific and Industrial Research Organization and the National Oceanography Centre, Southampton during the DISCOVERY cruise. It contributes to the CARINA synthesis project for biogeochemical and carbon system studies.
Use Cases
- Model ocean acidification by analyzing pH and total alkalinity (TA) relationships with other variables like temperature and salinity.
- Study nutrient cycles by examining correlations between nitrate, phosphate, silicate, and chlorophyll A concentrations.
- Trace water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12) measurements as transient tracers.
- Investigate biological productivity through chlorophyll A and phaeophytin profiles alongside nutrient data.
- Calculate carbonate system parameters (e.g., pCO2) from measured total alkalinity, pH, temperature, and salinity.
Strengths
- Multi-parameter suite includes 14+ chemical, physical, and biological variables per observation.
- Data collected as part of the international CARINA project, aimed at producing an internally consistent, merged dataset.
- Specific temporal coverage from April 23 to June 1, 1998, during a defined research cruise.
Limitations
- Limited temporal scope to a single 40-day cruise in 1998, providing a snapshot rather than a time series.
- Geographic scope is restricted to the specific cruise track of the DISCOVERY vessel in the North Atlantic Ocean.
- Sample size and spatial resolution are unknown, likely constrained by discrete bottle and CTD profile sampling.
